Be it known that I, EDWARDMCCREARY,

of Cohoes, in the county of lAlbany and State of New York,l have invented certain new and useful Improvements inj Machines `for Nap-v ping Cloth and other Textile Fabrics, of which the following is Va speciiicatn- V- My invention drelates to improvements ony the class of napping-machines in which a series of card-clothed napping-rollers are j ournaled in spiders secured to a driving-shaft deriving its motion from anyjsuitablemotive power; and it consistsof the novel mechanism herein described for effectingithelrotations of the napping-rollers around: their own axes independently of the rotations ,of the spiders; and it also consistsiof anovel construction of lubricator for automatically lubricating the journals of the napping-rollers. t

In the accompanying drawings, which form part of this specification and are herein referred to, Figure 1 is an end elevation of my napping-machine as viewed from the righthand end of the same; Fig.2, a partial front elevation of the right-handend of said machine; Fig. 3, a front'elevation of my napping-machine, the same being broken apart and having portions" removed to expose underlying parts; Figs. tand 5, elevations of the twodifferent endsof the machine with certain portions removed therefrom; Fig. 6,- an enlarged vertical longitudinalv section of portionsl yof my napping-l machine, showing construction of ,a flexiblefrimmed pulley for rotating the nappingfrollers and of the automatic lubricator for lubricating the j ournalsy of the nappingrollers;Fig. 7, a vertical secf tion of Fig. 6 at the lineX X; Fig.'8, a vertical section of Fig. 6 at the line YY; Fig. 9, an enlarged and detached vertical sectionof a portion of one of the spiders7 showing a journal-bearing for one of the napping-rollers and part of a lubricant-duct of my automatic lubricator; Fig. l0, a skeleton diagram showing the course of the goods through my napping-machine, and Fig. l1 a skeleton diagram showing thearrangement of the napping-rollers.

As represented in the drawings, A designates the frameworkof mynapping-machine, which may be constructed substantially as shown or in any form suited to the purpose.

Said ,framework is provided with journalfboXes l, inwhich a drivin g-shaft 2'is fitted to l rotate and impart the necessary motions to Ithe other operative parts of thermachine.

Upon, one end of-said, shaft are arranged pulleys 3, one of which is secured to the shaft and the other is fitted to rotate loosely there- `on. The tight pulley receives a driving-belt (not shown inthe drawings) that transmits lmotion lfrom a suitable source of motive power. The direction of the rotations of the shaft2 is indicated by any arrow on Fig. 4.

Bkindicates spiders secured to the shaft l and rotating therewith. Each of said spiders 'Vis provided with a series of journal-boxes 4 for the napping-rollers C and C' to revolve in, and, as indicated by arrows in Fig. S, the spiders revolve in one direction anmdiall the napping-rollers in the opposite direction. lt should be understood that there are two different series of the napping-rollers, all of the same diameter, and being arranged so that their axes will move'in the same circular path concentricall y to the center of the shaft 2, and being so arranged that the rollers of one series will alternate with those ofthe other series, the rollersofthe, twoseries revolving on their axes in the same direction, as indicated by arrows ,I on Fig. ll.- The rollers.. of the two L series are driven `from different ends, so that the means of yrotating them Iwill not interfere :with each other-that isto say, the rollers C are each provided with a small pulley 5, secured to one end thereof, and the rollers C' are each provided with a like pulley G, that is secured to the end of said rollers that is opposite-to the end of the iirst-named rollers.

IBy this varrangement provisionis made for revolving thejrollers C andC' at `different rates of speed when suchV differential speeds may"bedes irable The napping-rollers C, whichusuallyeffect the greater part in the operation ofy napping, have the points of the wires of their clothing bent forward in the direction in which said rollers are designed to travel, so as to take into the face of; the goods, and they are usually rotated at a higher rate of speed than the rollers Gi, which have IOO the points v of their wires bent backward in a direction opposite to the angle of thewires on the roller C, and while'the rollers Gf aid in the operation of napping the goods their principal function is to keep the goods spread out laterally in the operation of napping.

D and D are pulleys arranged to revolve loosely on the shaft 2. Said pulleys are located near opposite ends of said shaft and are fitted to revolve between the face of an adjacent spider B and a collar 7, secured on the shaft 2. To the periphery of each of said pulleys there is secured a flexible rim E, that extends toward the middle of the machine, so that they will overlap onto the small pulleys of the napping-rollers C and C', to which the pulleys D and D impart their motion. A sprocket-wheel Sis secured to shaft 2, and an endless chain 9 engages with the teeth of said wheel and with those of another sprocketlwheel 10, journaled on a stud 11, secured to the framework A. A pinion 12, secured to sprocket-wheel 10, gears into a wheel 13, secured to a shaft lf, so that the shafts Zand 1lwiil be rotated in opposite directions. A pulley 15, secured on the shaft 14, carries an endless belt 16, that passes over the fiexible rim of the pulley D, so as to press said fiexiblc rim into a positive frictional contact with the pulleys G, thereby rotating the rollers C', whose wires are at the time operating on the surface of the cloth. In order to obtain proper contact of the flexible rim of the pulley D while the rollers C are performing their functions, the belt 1G is deflected inward by passing it over an idle-pulley I7, as shown in Fig. 5, thereby forcing the flexible rim of the pulley D to bear upon the major part of the pulleys 6. A sprocket-wheel 1S, secured to the shaft 1i, carries an endless chain 19, that engages a sprocket-wheel 20, secured to a shaft S21, to which a pulley 22 is also secured. An endless belt is carried by said pulley and passes over the flexible rim of the pulley D to impart motion to the pulleys 5 and the napping-rollers C. The belt 23 is carried over an idle-pulley 2l for the purpose described in respect to belt 16. For the purpose of automatically lubricating the journals of the rollers C and C the spiders B are each provided with an annular oil-chamber 25 for containing the lubricant. Said chamber is provided with an oil-tight closure 2G, which Will prevent the lubricant from wasting therefrom. A feeding-tube 26 leads into the oilchamber and affords means for filling said chamber. Leading from the oil-chamber 25 there is a series of oil-ducts 27, one for each journal of the rollers C and C, and the outer end of each of said duets is provided with a tube 2S, which projects from the end of the duct to engage in a bushing 2f) of the journal-bearings 4 for the napping-rollers, and thereby the said bushings will be positively retained in their proper places in the spiders B. The outer-end of each tube 2S is provided with a porous plug 30, which bears against the journal it is designed to lubricate, and thereby a perfect lubrication of the journals will be effected and a waste of lubricant prevented. By this means a much better result is obtained than by the ordinary capillary devices commonly employed for such purposes. In practice porous leather-has been found to be a good material for the porous plug.

Tension-beams F are arranged at the front of the machine for the purpose of producing a requisite degree of tension on the goods undergoing the operation of napping. Said beams are preferably carried by adjustable arms 31, pivoted, as at 32, to brackets 33, secured to the framework A. The arms 31 are preferably pivoted to allow an adjustment of the beams F to different angles in respect to a vertical line. G is a tension -roller journaled in bearings 34, over which the goods are passed after going over the tension-beams F, and in order to obtain a resistance to the rotation of said roller, which is rotated by the goods, a friction-band 35 is passed over it. One end of said friction-band is connected to a stationary part of the machine, as at 36, on Fig. 2, and its opposite end is provided with weights 37, which can be adjusted as occasion requires.

II designates feed-rollers by which the goods are fed to the action of the nappingrollers of the machine. Said feed-rollers are rotated in the following manner: A sprocketwheel 38 is secured to the shaft ll and an endless chain 39, which engages with teeth of the last-named sprocket-wheel and also engages the teeth of a sprocket-wheel 40, fitted to rotate on a stud 41,that is stationary in the framework A. Secured to the sprocket-wheel 40 there is another sprocket-wheel 42,that engages an endless chain 43, that also engages with the teeth of a pair of sprocket-wheels 4st, secured to the protruding ends of the shafts of the feed-rollers II. The diagram shown in Fig. 10 illustrates the course of the goods through the machine. The goods indicated by a heavy line first passes over the tension-beams F, from thence over the tension-roller G,and,afterpassing under the foremost feed-roller II, over the cylinder of napping-rollers C and C', whereby the goods are subjected to the operation of napping under the second feed-roller II, and usually against a tension-beam F, from which the goods may lead over a series of rollers (not shown in the drawings) to be delivered into reeepta cles prepared for that purpose or disposed of in any other manner that may be preferred.

Having thus described my napping-machine, what I claim as my invention, and dcsire to secure by Letters Patent, is-

1. In a napping-machine, the combination, with a napping-cylinder provided with two independent series of napping-rollers-the rollers of one series alternating with the rollers of the other series and the rollers of one series having pulleys secured to one end of the rollers and the rollers of thc other series having pulleys secured to the opposite end, of driving-pulleys arranged at opposite ends of the napping-cylinder and fitted to rotate IOO IIO

loosely on the shaft of the latter; e'aeh driving-pulley having a liexible rim extending therefrom so as to overlap onto and take in frietional Contact with the corresponding roller-pulleys, as speeied.

2. ln a napping-machine, the combination of a series of napping-rollers each having; a pulley on one of its outer ends, a drivingpulley provided with a flexible rim extending therefrom and adapted to overlap' onto and take in frietional Contact with each rollerpulley of the series of napping-rollers, and a rdriving-belt arranged to bear upon the outer face of the flexible rim of the driving-pulley so as to force down said flexible rim into positive frietional contact with the roller-pulleys, as specified.
